sPEoIrIoAr-Io'iv forming part of Letters Patent No. 382,064, dated May1, 1888.

Application filed December 15, 1886. Serial No. 221,626. (No model.)

To aZZ whom, it may concern:

Be it known that I, CHAUNsEY L. S. WALKER, a citizen of the UnitedStates, residing at Newark, in the county of Essex and State of NewJersey, have invented certain new and useful Improvements in Machinesfor Forming Saw-Handles; and I do hereby declare the following to be afull, clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame, reference being had to the accompanying drawings, and

more quickly than heretofore, thereby reducing the cost of manufacture.

The invention consists in an improved machine for forming saw-handlesand in thearrangements and combinations of parts thereof, substantiallyas will be hereinafter set forth, and finally embodied in the clauses ofthe claim. 7

Referring to the accompanying drawings, in which like letters indicatecorresponding parts in each of the several figures of the four sheetsthereof, Figure 1, Sheet 1, is a side elevation of my improved machine,showing in dotted outline the different positions of a saw-handle andslide-rest in the operation of forming a portion of said saw-handle.Fig. 2 is an enlarged detail of an arbor, shaft, or mandrel providedwith a cone-pulley and adapted to hold the cutters. Fig. 3 is an endview of my improved machine, showing the cutters mounted in position onsaid arbor, shaft, or mandrel. Fig. 4., Sheet 2, is a plan of the same;and Fig. 5 is a section through line X, Fig. 4.. the sliderest beingremoved. Fig. 6, Sheet 3, is'an enlarged detail of a certain cam-rod forraising orlowering the center of pivotal motion of said slide-rest. Fig.7 is an enlarged detail sectional view through line Y, Fig. 4, Sheet-21Fig. 8 is a plan view of a blank or cutter carrier to which are attachedthe cutters for forming certain parts of said handle. Fig. 9 is a sideelevation of the'same; and Fig. 10 is a section through line Z, Fig. 8.Fig. 11 is a plan of certain guides attached to a pi'votallyarrangedrest or plate; and Fig. 12 is a section through line V, Fig. 11. Fig. 13is a plan view of one of the pivotal centers of the slide-rest; and Fig.14 is an end view, partly in section, showing the said centers inconnection with saidcam'rod, whereby-said centers can be adjusted to anydesired height. Figs. 15, 16, 17, 18, and 19, Sheet 4., are sideelevations of certain cutters for forming the beads on said sawhandle.Fig. 20 is a section through line W, Fig. 19; and Fig. 21 is a sideelevation of a cutter or knife to be used in connection with the form ofcutter-carrier shown in Figs. 8, 9, and 10, Sheet 3. Fig. 22, Sheet 1,is a side elevation of a modification of the pivotal center shown inFigs. 13 and 14., Sheet 3.

Insaid drawings, A represents the bed of my improved machine, which maybe of any convenient form and may be provided with arms or supports B Bnear one end to receive an arbor, shaft, or mandrel, as O. Said arms orsupports may be and preferably are slotted near the top thereof toreceive adjustable bearings D for said shaft 0. Said bearings, as hereillustrated, are slotted, as at E, Fig. 5, and secured to said arms orsupports B by a screw passed through said slot in the ordinary manner,thus allowing said arbor, mandrel, or shaft 0 to be moved horizontally alimited distance in either direction. Said arbor, shaft, or mandrel isadapted to receive a pulley, as F, and cutters, as G G and H H, and maybe provided with a screw-thread and nut at one end thereof, as indicatedin Figs. 2 and 5, or a wedge-shaped collar and pin, as in Fig. 3. Thusby tightening said nut or wedge-shaped collar the cutters are heldfirmly to the shaft, so as to be turned thereby when said shaft isdriven by said pulley. Said bed A provides a bearing for a sliderest, I,and a guide, J, the latter working in a suitable groove in said bed A,and said rest I is also provided witha bushing or strip, K, Fig. 3, tosupport the opposite side of said rest. Thus said rest is guided in astraight backward and forward motion at or approximately at right anglesto the central line of the shaft, arbor, or mandrel carrying thecutters. Said slide-rest I is provided with supports L at the sidesthereof, which serve to carry the bearings M of a pivotallyarrangedplateor carrier for thesaw-handle. Said plate or carrier N is designedto act as a rest for the saw-handle, which is held in close relation tosaid plate N by means of a clamping device consisting of a lever, as O,fulcrum, as P, and cam or eccentric, as Q, the latter being operated bya handle, as S. By this construction when the handle S is raised thesawhandle may be inserted. Then by pressing .the handle downward thesaid saw-handle is held in a fixed relation to said pivotally-arrangedplate or carrier N. .Said plate N is provided with a handle, as R, inorder that it may be more easily turned on its pivot and made tooperate, as will be hereinafter referred to. Said supportsLalso providepivotal bearings for a guide plate, as T, provided with guides U, asindicated in Figs. 1, 4, 11, and 12. Said guides (in this case three innumber) may be secured to said plate T by means of set screws passingthrough a slot in said guide, thus allowing them to be adjusted to serveas guides for saw-handles of different sizes. One of the pivotal centersof the guideplate T extends beyond its bearing in said support L, asshown at it, (see Fig. 1,) and is provided with an arm, A, having anadjustable wedge-shaped extension, A. Said arm A is rigidly attached toone of said pivoted centers and is provided with a set screw, wherebysaid wedge-shaped extension A may be adjusted, and is adapted to engagea pin or other projection on a standard, as B, attached to the bed A,Figs. 1, 4, and 7. Said supports L are suitably slotted to receive acam-rod, O, as indicated in Fig. 14. The pivotal center of the plate Nis fixed to vertically-movable dovetailed pieces D, which rest on saidcam-rod, and may be raised or lowered by moving said cam-rodhorizontally or longitudinally, as is evident by reference to Figs. 6and 14; or the distance between the plate N and its pivotal center maybe changed by securing the bearing M to the support L and having themovable sliding piece D and cam-rod 0 attached to the plate N, as shownin Fig. 22, Sheet 1. Thus any height of pivotal motion may be securedwithin certain limits of the plate N by adjusting said cam-rod G with aset-screw or other means, as will be understood.

The cutters G, as shown in detail in Fig. 21, Sheet 4, may be andpreferably are twelve in number, arranged in sets of four and secured bymeans of screws or otherwise to a cutter carrier or form, as F. (Shownin detail in Figs. 8, 9, and 10, also shown with the knives attached inFigs. 1, 3, and 4.) Said cuttercarricr has the inclination or eachquarter of it is tapered, as indicated in Figs. 9 and 10, in order togive the knives the best cutting position in relation to the saw-handlewhen attached thereto. Said cutter carrier or form is also provided witha perforation to allow it to be mounted upon a shaft, arbor, or mandrel,as shown in Figs. 1, 3, 4, and 5.

The cutters H are five in number and are circular and provided withteeth or cuttingedges similar to theteeth of asaw, except that they areall on one side of said cutter instead of alternating,asin a saw. SaideuttersHare adapted to fit on said arbor, shaft, or mandrel O by beingsuitably perforated. Allsaid cutters are arranged on said arbor, shaft,or mandrel in the order shown in Figs. 3, 4, and 5, and are adapted toout the beads and form portions of the saw-handle contiguous thereto, asindicated in Fig. 4, it being preferable to have the periphery ofsaidbeads curved; hence the pivotal motion of the plate or carrier N on saidslide-rest I is used to give the proper contour to said beads,asisindicated in Fig. 1.

When the slide-rest is drawn back, the arm A is automatically raised bycoming in contact with a lug or pin on the post B, (said lug or pin isat or near thetop of said post B,and is indicated by a dotted line andlettered F in Figs. 4,) thus raising the guide-plate T to the positionshown in Fig. 1, and by raising the handle S, which operates the leverO, a sawhandle blank may be inserted under said lever 0 and in theproper position by allowing it to come in contact with the guides U,which are so placed as to insure such result. Then said handle S may belowered, thus clamping said saw-handle, and the slide-rest pressedforward, with the handle R lowered, so as to bring the saw-handle intothe position shown in dotted outline in Fig. 1. The guide-plate dropsout of the way automatically after the arm A passes the post B, and thecutters be ing revolved by means of a belt and pulley, as F, theslide-rest is pressed forward until the stop E engages the edge of theplate A. Then the handle R is raised, which brings the sawhandle intothe second position shown in dotted outline in Fig. 1, thus completingthe cut, as will be readily manifest. When the rest I is drawn back, theguide-plate T and guides U are brought again into position, as shown inFig. 1. The finished handle may then be removed and a handle-blank beinserted and put through the same operation.

Suitable adjustable stops, as E,'Fig. 1, are, as here indicated,arranged at the ends of the slide-rest, in order that the feed movementmay be adjusted so that the cutters will make the depth of cut desired;or other suitable means may be employed to limit the depth of cut orforward motion of the slide-rest, as will be understood.

The cutters may be separated any desired distance on the shaft, arbor,or mandrel C by means of washers, as D, or a number of washers, as shownin dotted outline in Fig.2, thus separatingthe cutters, so that thebeads may be cut at the proper place in saw-handles of different sizes.

I do not wish to be understood as limiting myself to the exact form andproportion of parts as herein shown, as it is evident that oted holdingdevice for holding and. guidingsaid saw-handle to said cutters,substantially as and for the purposes set forth.
